What can I expect?

As you know I blew a hole in a piston and decided to do some head work as well.

The basis was 75hp/130ft lbs to the wheels with a 2.77. The only head work at that point was a 3 angle valve seat job.

What was done this time around was:
-Smoothed and polished the carb inlet
-3 angle backcut on the intake valves
-Hardened exhaust seats (not expecting gains from this
-Mating surface milled .040
-Exhaust port divider installed
-4.0L springs and retainers

In not asking for how much power will it gain exactly, but can anyone give me a rough idea. Also the 2.77 has been replaced with a t5

Honestly, I doubt you'd see much more than a few HP difference. What you will see is slightly better engine response and better economy.

The car will feel more peppy however with the addition of the T5. The T5 gearing is a HUGE improvement from the 2.77 and won't bog the engine down so much with the ratios.

Oh I know about the t5 difference, thats an older mod I just included it because it was something that was done since having the car dynoed
